I think GTO means "Gran Turismo Omologato", it is the Italian term for the homologation of the car in racing. The rules of some racing series apply that the race car is a road car or slightly adapted road car, so the manufacturers make a limited number of those road cars to let the race car be allowed in the races.

Thanks wow thats good to know bro.. although we need to gather more info with regards with this code..appreciate your time..

just to be pedantic the engine code '4G63BT' was never officially used by Mitsubishi. In fact the B (let alone the T) is not used at all on the 4G63 block. The B comes from the older naming convention when the engines were stamped G63B, G32B, G54B etc. When they changed over to 4G63, 4G32, 4G54 the B was dropped. You wont find the T stamped on the block to designate turbo either.

sorry for the thread hijack but i'd also like to know if anyone here is aware of a manual transmission with torque converter, yes, manual transmission with torque converter! , i just discovered that on an 83 galant sapporo(a154a) with 4g63, i wonder if there's any other mitsubishi models that came with it and how does it work, i'll post pics of it soon
